GRAND RAPIDS – An undercover child-pornography investigation that stretched from New Haven, Conn., to New Zealand has resulted in the arrest of an East Lansing man who is on the state sex offender registry for crimes in Florida.

Patrick Dale Wiseman is named in a federal criminal complaint that was unsealed today upon his arrest, court records said.

The complaint, alleging distribution and possession of child pornography, showed – through Wiseman’s Internet chats - his sexual preoccupation with children only months old, FBI special agent Karl Haws wrote in the 8-page document.

Wiseman also said he enjoyed hurting children, Haws wrote.

Haws listed many disturbing titles of photos or videos seized by police.

Wiseman had his first court appearance today in U.S. District Court in Grand Rapids. A detention hearing is set for Friday.

Haws said an FBI special agent in Connecticut last March browsed Wiseman’s shared folder in a peer-to-peer file sharing program, and downloaded 133 files whose names indicated they contained child pornography. The images included children believed to be as young as 6 months old being sexually abused, records said.

Police linked Wiseman’s IP address to the crime, records said.

During an undated chat with an undercover New Zealand police officer, Wiseman allegedly claimed he was abusing a relative’s child, and spent time in the Phillipines where he engaged in sexual activity with children.

Homeland Security Investigations determined that “Wiseman had traveled to Southeast Asia a few times over the past three years and records indicated that he was married to a woman in Manila,” Haw wrote.

After a search last July of the suspect’s home, a forensic examination of his laptop computer showed the existence of 800 photos and 133 videos of suspected child pornography.

Last month, another FBI special agent in Maryland, working undercover online, accepted an invitation from a user later identified as Wiseman, the FBI said. Wiseman talked about a close call a year before, presumably when police searched his home.

Wiseman took part in lengthy, graphic chats about his preferences, records said. He also talked about going to the Philippines, the FBI said.

Wiseman was convicted in 2002 in Florida on two counts of “possess, photograph, film or other representation that knowingly includes sexual conduct by child,” the FBI said in court records. His information on the sex-offender registry was up to date, records showed.

The criminal complaint, issued a week ago, was unsealed upon Wiseman’s arrest today.
